Here is a five minute bar chart of e-mini day session trading. I thought today would be a bullish day with a day session range of 945-965. Instead sellers took control right from the opening. At the moment it looks like prices above the 950 level have been rejected and that the short term trend is downward. Even so, I don't see any unusual volume on this break so I think we have seen most of the day's range. I now estimate today's daytime range as 935-950.
Since I am long a full position in what appears to be a downtrend I want to sell out on a rally if I can. The most I can hope for today is the midpoint of today's range which at the moment stands at 944 (purple dotted line). I am leaning on midpoint support near 936 near which I expect the day's low to develop.
